Formula boric acid Science News for KIDS

Qhov tsab xov xwm no yuav qhia txog boric acid, uas yog dav siv nyob rau hauv ntau yam teb ntawm kev ua si thiab yog lub npe hu rau yuav luag txhua leej txhua tus. Formula boric acid yog tsis tshua muaj tej yam yooj yim mus khw. Cov tsab xov xwm yuav muab suav hais tias ib tug general yam ntxwv zog thiab boric acid, thiab nws teb ntawm daim ntawv thov nyob rau hauv cov xwm.

Yuav ua li cas yog boric acid

Formula boric acid Science News for KIDS paub ntau. Nws yog es tsis muaj zog piv rau lub "lug txhawb cov miv." Nws yog kev koom siv rau tshuaj lom neeg thwmsim nyob rau hauv cov tsev kawm ntawv. Formula boric acid - H ₃ Bo _3.

Boric acid - ib tug crystalline hmoov, uas yog tsis muaj kob thiab ntxhiab. Molecules triclinic fawm kib lattice sib thooj, los ntawm hydrogen bonds thiab tsim tiaj khaubncaws sab nraud povtseg. Yog li lub tsev molecule thiab boric acid.

Tam sim no cov ntaub ntawv uas muaj zog me ntsis acid - tsis zoo soluble nyob rau hauv cov dej. Ib tug feature yog hais tias lub cuab yeej ntawm acid H ₃ Bo ₃ txuas accession anion ntawm lub hydroxyl pab pawg neeg. Nyob rau hauv lwm yam acids cai muaj peev xwm phua tawm H + proton.

Nyob rau hauv lub tsim ntawm hydrogen boron B (HSO _{4) 3,} uas yog heev slaboustoychiv, boric acid tej zaum yuav es tsis muaj zog tej yam tshwm sim amphoteric. Yog hais tias lub compound raug thermal kev nyuaj siab, boric acid muaj peev xwm sawv ntawm dissolving lub hlau oxides, uas ua rau tsim ntawm ntsev. Peb mis rau cov tshuaj compound nyob rau hauv lub xub ntiag ntawm sulfuric acid nyob rau hauv feeb meej daim ntawv no, muaj peev xwm tsim esters:

Thaum lub sij hawm hauv chav kawm ntawm tus txheej txheem ntawm neutralization nrog alkalis nyob rau hauv dej dlaws, orthoborates muaj (NPAWG _{3) 3,} tsis tsim. Qhov no tshwm sim yog piav los ntawm lub fact tias lawv yog yuav luag tag thaum lub sij hawm neutralization hydrolyzed vim hais tias ntawm excessively me me ntawm constants [B (OH ₃₎ -. Raws li ib tug tshwm sim ntawm cov tshuaj tiv thaiv no nyob rau hauv cov kua pib tsim ntsev polibornoy acid, e.g., metaborates, tetraborates thiab lwm tus:

Yog hais tias lub alkali tam sim no nyob rau hauv excess, lawv yuav mus nyob rau metaborates:

Thiab tetra- thiab metaborates tau hydrolysis, tab sis nyob rau hauv kev sib piv nrog orthoborate muaj ib tug tsawg degree ntawm inclination.

Boric acid nyob rau hauv cov xwm

Boric acid, uas tshuaj mis H ₃ Bo _3, feem ntau pom nyob rau hauv qhov nyob rau hauv ib tug ntau heev free xeev - ib tug mineral sassoline. Ntxiv mus, qhov no acid yog ib feem ntawm tus dej kub ntawm zoo siv txhua yam ntuj tso qhov twg los. Kuj muaj loj npaum li cas ntawm H ₃ Bo ₃ muaj nyob rau hauv underground mineral dej uas yog cov tsis tshua pab rau kev kho mob.

Siv H3Bo3 txiv neej

Raws li sib tham saum toj no, boric acid mis yog paub tias yuav luag txhua leej txhua tus. Qhov no yog vim ib tug ncaj ntau yam ntawm nws cov kev siv nyob rau hauv lub neej txhua hnub, nuclear physicists, Jewelers, electricians, cov kws kho mob thiab zoo tib yam cov pej xeem - tag nrho siv boric acid. Nws yog siv raws li ib tug antiseptic thiab nplaim retardant. Boric acid pab tiv thaiv kom ntoo, ntxiv mus rau lub teb chaws ntawm chiv.

Tshuaj Nyiaj siv raws li ib tug neutron absorber nyob rau hauv ib tug nuclear reactor nyob rau hauv cov tshuaj H ₃ Bo ₃ tov uas muaj ob feem pua yam khoom uas yog siv raws li ib tug antiseptic rau daim tawv nqaij kab mob li cas nto.

Kev pab txog siv nws li zoo hom tsim tawm. Nrog nws ua ib qho kev acidic ib puag ncig rau tus fixer.

Casters boric acid yog siv raws li ib tug phau ntawv thaum lub sij hawm lub cub tawg hauv ob sab phlu.

Nyob rau hauv lub neej txhua hnub tus neeg siv nws los tswj kab.

Acid yog dav siv nyob rau hauv tshuaj pleev ib ce rau qhov kev kho mob ntawm cov teeb meem ntawm daim tawv.

Nyob rau hauv cov zaub mov kev lag luam nws yog lub npe hu ua boric acid additive E284, thiab nyob rau nws cov hauv paus chaw soj nstuam npaj tsis daws teeb meem.

Formula H3Bo3 boric acid yog siv nyob rau hauv qhov siv thiab ua ceramics, iav, iav fibers thiab fiber.

Ib tug plurality ntawm chav npaj ntawm ATX D08AD ib tug ntawm cov Cheebtsam yog boric acid.

Jewelers siv nws thaum lub sij hawm brazing alloys, uas muaj xws li kub, raws li ib lub hauv paus flyusof soldering.

Koj boric acid yog txaus ntshai?

Boric acid yog tsis txaus ntshai thiab tej zaum yuav ua mob tsuas yog thaum lwj liam siv. Tuag concentration nyob rau hauv lub cev ntawm tus me nyuam yog los ntawm 4 mus rau 5 g, thiab nyob rau hauv lub cev ntawm ib tug neeg laus yog hais txog 15-20 g H ₃ Vim Bo ₃ yog tsis tas txaus ntev lub sij hawm, tej zaum nws yuav maj mam noog mus tuag koob tshuaj ntawm heev thiab kev tsis daim ntawv thov.

Nyob rau hauv xaus peb yuav hais tias H ₃ Bo ₃ yog ib qho tseem ceeb tshuaj nyob rau hauv tus tib neeg lub neej thiab kev ua si.
